fication.

This invention relates to that class of locks the case of which is combined withand forms a part of ahasp, said hasp and lockbeing adapted to engage with a stud or staple, and obviate the necessity of using a padlock which can be detached and mislaid orlost.

Theinvention consistsin the combinin gof the following parts, the novel features of which will be more particularly set forth in the claim at the close of `this specification Alock-case the back plate of whichis extended on one side to form a hasp; a bent bolt-plate'havinganotched iiange or web on which the key operates to move the bolt plate back and forth; a springactuated tumbler for lookin g the bolt-plate at either cxtremity of its range ofmotion; a springfor moving the bolt-plate in one direction 5 an arm or trigger pivoted within the lock-case and extending to the outside thereof, by which the boltplate, when the bolt is retracted, can be freed from the tumbler and the lock locked without using the key. i

In the annexed drawings, Figure l is a `perspective View of a chest provided with one of Fig. 2 is a plan of myhasp-lock, theface-platebeing removed and reversed. Fig.3 is a similar view, showing the bolt retracted. Fig. 4 is a plan. showing the bolt-plate. Figrepresents details of the tumbler. Fig. 6 is aview of the face-plate reversed.

Fig.`7 is the key.

` The same letters of reference are used in all the figures in the designation of identical parts. The hasp A is formed from an extension of the back-plate B ofthe lock-case, said plate being provided with a slot for the reception of a staple, with which the bolt engages. lThis Application filed October 27, 1880. (Model.)

`hasp may be provided with a hinge-joint and secured to a door or other object by bolts or screws a, as shown; or it may be made in one rigid piece, provided with a hole near the end, and securedwith a staple in such manner as to admit of its being swung out away from the t oor.

The walls B of the lock-case in this instance form a square, and are secured to the back-plate B by bolts, in the manner ordinarily practiced in the construction of such devices.

The face-plate B2 of the lock is provided with the usual key-hole.

The bolt-plate D, extending entirely across the lock-case and provided at its ends with legs d, is seated within said case, its legs d fitting so closely to the sides of the case as to prevent wabbling of the plate when it is slid back and forth. One leg of this bolt-plate is provided with a flange or web, D', having a notch, d', cut in its edge, and being also slotted at d2,so that it can slide' up and down on the post H, fixed to the back-plate of the lock. This flange is provided at its upper end with a post, d3, on which is pivoted a tumbler, E, having a slot, e, provided on one edge with notches e' c2. The tumbler E is provided at its free end with an arm, E', terminating near the face-plate ot' the lock with a spur andshoulder, as shown in Fig.5.

O11 the post d3 is seated a bifurcated` spring,

E2, one leg of which bears outwardly against one leg, d, ot' the bolt-plate D, while the other leg bears against the arm E of tumbler E and tends to force the notched edge of the slotein said tumbler against the fixed post H, which projects up into said slot.

To the plate D is secured the bolt, in such position that it can be shot across the slot in the back-plate B of the lock through the staple I.

A spring, F, of any suitable form, is seated against the upper wall of the lock-case and acts to force the bolt-plate D down to the position it occupies when the lock is locked. p

To the inner side of the face-plate B2 is pivoted a trigger, Gr, curved as shown, its free end extending down through a slot in the lower wall of the lock-case. This trigger occupies the space between the shoulder ot' arm E' of tumbler E and the face-plate ot' the lock, and engages with its convex edge the spur on said arm E, so that by moving the exterior end of IOO blcr pivoted to the bolt-plate, the xed post for en gagi n g the tumbler, and the trigger for freeing the'tumbler from the post, so that the bolt can be shot by its spring.

In testimony whereof I affix my si gnature in presence of two witnesses.
